GATE VALVE FOR SAND AND GBAVEL DUMPS.

Application filed August 2, 1921.

To all whom it may concern:

Be it known that 1, WILLIAM M. humans, a citizen of the United States,residing at Reno in the county of Washoe and State of Nevada, haveinvented a new and Improved Gate Valve for Sand and Gravel Dumps, ofwhich the following is a specification.

This invention has reference to an improved means for regulating theoutflow from sand and gravel dumps, ore piles, and the like, and it hasfor its purpose to provide a means of the general character stated oi acomparatively inexpensive constru tion. that is more especially designedfor regulating the quantity oi sand or gravel, either in the wet or drycondition, which gravitates from the dump onto conveyers for deliveringthe material at some desired place.

Generically, my invention comprehends an improved arrangement 0? a dumpretaining wall having an outlet for the passage of the material as itgravitates from the dump, a receiving trough or conduit from which thematerial, as its drops into the receiving trough or conduit, is carriedby an endless conveyor and elevated to a place for use or for loadinginto cars or wagons for being conveyed to the place of use.

My invention also comprehends a peculiarly arranged outlet or passagethrough which the material in its escape from the dump in position forbeing gathered by an Lip-carrying conveyer and a control or gate valvefor the said outlet or passage whereby the dropping oil? the material,as it gravitates through the retaining wall outlet is regulated to fiowrapidly or slowly, as conditions for moving the out passing material maymake necessary.

lVith these and other objects in view, as will hereinafter be apparent,my invention comprises certain features of construction and novelarrangement of parts, all of which will be explained in the "followingdetailed description, specifically stated in the appended claims, andillustrated in the accompanying drawings, in Which Figure 1 is an endelevation of a portion of the dump retaining wall having the out let,the gathering chamber that receives the material which gravitatesthrough the out let, and the adjustable gate device.

Serial No. 189,336.

Figure 2 is a longitudinal section of a port on of a sand and graveldump, the retaining wall having the outlet, and the gate valve devicethat controls the droppin of the material into the convevcr reccivinconduit or trough, V b

Figure is a detail horizontal s ction on the line 3-3 of Figure 2.

Figure 4 is a perspective view of one form of the gate valve shittinglever used. in connection with my peculiarly arranged gate valvedevices. I i

In the drawings, which illustrate a pract cal arrangen'ient of myinvention, a portion of a sand and gravel dump 1 is shown in Figure 2,which may be an ordinarv ground surface incline, but is preferablyprovided with a solid or concrete surface for facilitating the travel ofthe sand and gravel toward a retaining wall 3 which, in practice, isbuilt up of heavy wooden tinibers suitably braced and which, along theupper base line of the dump, has an outlet 4-, preferably square, asshown in dotted lines on Figure 1.

By referring to Figures 1 and 3 of? the drawings, it will be noticed amaterial receiving compartment 5 is formed ust outside the passage 4: inthe wall 3 and the saithcompartment is shaped by a metal housing 6 whichincludes a face wall in parallelism with the wall 3, and an end orangled wall "which has a lateral. flange 61 whereby to secure the saidend of tlie housing (by screws '7) to the retainingwall 3, the other endof the housing being liXedlv secured by large screws 8 that take intothe uprights or framing timbers 9 and which constitute a part of thewall 3.

The top and the bottom of the chamber 5 may be open, as shown. and theopening in the bottom, which is located ust abovh the receiving troughor conduit into which the outflow of the material is fed, is controlledby a gate valve 10 of metal whose opposite edges rise in guide grooves11 formed, at the inner edge, by a cleat 12 attached to the outside ofthe wall 3 just below the bottom opening l and a cross plate 13 se curedto the bottom edge board. the said plate 13 constituting the bottom faceof the opening 4t. The guide for the outer edge of the valve 10 is"formed by a metal cross member 15 whose opposite ends are screwed ontothe uprights 1616, and an angled strip 17 which is bolted to the members16, as shown.

The valve plate 10 is of a length to extend some distance beyond the endof the housing 6 and the it'ree end thereof has a pair of apertures 1010 near the outer edge, the purpose of which will presently appear.

7 2O designates a cross bar which extends horizontally over the housing6 from one end upright to the other of the framing, and at a pointmidway the end 6 of the housing and the adjacent upright or post anelongat ed U shaped bearing 25 is projected inwardly from the crossmember 20, which member is located near the upper end of the housing 6,as shown.

30 designates a long lever having a bifurcated lower end 31, a handle 82at the upper end and for clearance, when using, the saidlever is bentmidway its length, as best shown in Figure 4E.

The lever 30, when the parts are operatively assembled, fits between theloop bearing 25 with its forks 31 in engagement with the apertures 10-10in the adjacent end of the gate valve 10, it being obvious by referringto Figure 1, that the limits of adjustment of the gate to the openand-closed positions are indicated by the full and dotted lines positionof the lever. I

In the drawing, the lower end of an upgoing endless scoop chain conveyer18 is shown, which is arranged to take up the material through thebottom of the chamher 5. Under some conditions, the endless conveyer isnot necessary since the material, as it gathers in the conduit, can bereadily removed by shoveling it into wheel barrows or wagons loadedadjacent to the sides of the conduit.

From the foregoing description, taken in connection with the drawings,the construction, the manner of use and the advantages of my inventionwill be readily understood by those familiar with the operation ofmloading sand and gravel dumps.

Owing to the peculiar arrangement of the receiving chamber 5 and theadjustable gate valve 10 in the bottom thereof, simple and easilymanipulated provision is made for regulating the passage from the saidreceiving chamber into which the material flows from the outlet 4. j

The discharge passage from the receiving chamber 5 being always smallerthan the outlet 4 in the retaining wall 3, the said smaller passage isreadily increased or diminished by means of the lever 30 to suit thecondition of the material being worked, whether wet, dry or partly wetand dry,and which flows through the aforesaid outlet 4.

What I claim is I 1. In an ofiitake for sand and gravel dumps and thelike, the combination with a retaining wall along the bottom of thedump, the said wall having an outlet at the bottom of the dump throughwhich the material from the dump is discharged by gravity; of a housingthat constitutesa chamber into which the material as it gravitatesthrough the retaining wall outlet is received, a gathering conduit belowthe receiving chamber, the said chamber having a 'discharging opening inthe bottom thereof through which the material passes into the conduit,the said opening being of less area than the opening in the retainingwall.

2. As an improvement in means for loading material from Send and graveldumps, the combination with a retaining wall against which the materialon the dump constantly gravi'tates, the said wall having an opening oifixed size through whichthe material continuously flows, a chamber onthe outside of the wall into which the material flowing through the walloutlet is received, the said chamber having a valve gate controlledbottom discharge, a conduit below the valve bottom discharge of thereceiver into which the material passing from the dump is collected andfrom which it is conveyed, the said valve moving in a horizontal planeover the bottom opening of the receiving chamber and having one endextended beyond the said chamber, the chamher being formed by a housingincluding an angled end secured to the. retaining wall and whose otherend is secured to abeamj attached to the outside of the wall, a braceiember that extends across the housing and is attached at its oppositeends to upright timbers that constitute a part of the wall, an elongatedU shaped bearing that projects inwardly from the, said brace member, theexposed end of the gate valve having a pair of apertures, and a leveradapted for being removably. fulcrumed in the U shaped bearing andprovided with a forked lower end for engaging theapertures in the gatevalve,
